We can compare to previous results by converting our expansion parameters \(r_1\)  and \(s_0\)  into the expansion parameters appearing in \(A(r)=a_2r^2+...\)  and \(B(r)=b_2r^2+...\) . From \(a_2=r_1^{-2}s_0^{-2}\)  and \(b_2=s_0^{-2}\)  we have \(a_2\approx 0.0657q^2/M^4\)  and \(b_2\approx 0.00089q^2/M^4\) . These results are similar to previous results at smaller \(M\) , as is the result for \(\zeta \)  in () [1]}.
